• The M/M-scores are cor-related to the sunspot curves.

• Over many years the M/M records were only set by U.S. guys.

The BCC-2000 Project

• The idea to set up a new world record was born in 1989 after the LX7A operation was successfully completed. But: we had to wait for the peak of the next sun spot cycle which was predicted to be around the year 2000.

• Zone 33: can be reached by overland route, proximity to Europe, good propagation's .

• 1995: DL5MAE & DL6RAI are travelling to Madeira, CT3

• 1997: DL2NBU & DL6RAI are travelling to Ceuta, EA9; DK3GI visits the Canary Islands , EA8

• 1998: DL6FBL receives an invitation to Rabat/Morocco.

• May 1999: DJ9MH, DL6FBL and DL1MFL take part in the CQ-WPX-Contest from Morocco.

• September 1999: DL6FBL & DL8WPX take part in the WAE-DX-Contest and explore a new QTH. They found a new QTH (Hotel Firdaous) and checked it for a M/M operation.

• October/November 1999: First try to set up a new world record CN8WW.

• Allocation of responsibili-ties to many members.

• Communication via BCC2000-WEB-site and CN8WW-mailing-list.

• Co-ordination and logistic planing via Internet.

Logistics

• The majority of equipment is owned by the participants of the activity . The rest was bor-rowed from BCC members or sponsors .

• At three different logistic centers (Goch, Fulda und Windach) the material was collected and stored before and after the contest.

• We created a special numbering scheme to identify the material during packing and un-packing .

• Every station was planned in any detail.The bill of material contained 720 items with a total weight of 10 tons .

• material transportation was done with a truck and VW-van on overland roads. Driving time: approx. 50 hours.

• The rest of the gang flew in from different locations with KLM Airlines via Amsterdam airport.

BCC-standard

The BCC standard was created to insure com-patibility of the different plugs and interfaces for a multi op operation.


page 29

TS-850SAT

TS-850SAT

To ensure fast replacement in case of a transceiver failure all stations were equipped with a TS 850-SAT from Kenwood. During many BCC activities this transceiver has turned out to be very reliable. From the operators or BCC members we had a total of 16 TS850-SAT during the SSB contest and 14 TS850-SAT for the CW part.


page 30

EMC

To prevent current flow on the outside of the coax cables which causes unwanted radiation and signal pick up we used current baluns. The current balun consists of 25 toroids type B64290-K618-X27 and 0,5m RG-213.We made a couple of these current baluns and used them at different points in the set ups.

EMC

Additional Measures:

• Low pass filter with additional notches on the higher bands developed by DL7AV/DK4VW (first version developed in 1987 for HD8EX )

• 100-watt-filter (Dunestar)


page 32

EMC

In the year 1997 and 1998 we built about 100 BCC-Preselectors. Simple design, use of standard components and high efficiency are the main advantages of this device.


page 33

headphone amplifier

Enables both operators to access both receivers audio. In addition you can use it in stereo mode (means: left ear - left RX and right ear - right RX) .The volume of each radio can be adjusted separately.

R1 = left radio on both earsR1+R2 = left radio on left ear, right radio on right earR2 = right radio on both ears

page 35

el. bug

How it Works: The very first symbol is delayed by approx. 40 ms, all following sym-bols are synchronous with the paddles.With this circuitry hot swit-ching of transceiver and power amplifier is avoided even with high speed telegraphy.

• First use: WAE-DX-Contest 1998 DLØCS• avoiding hot switching• two modes: with/and without dot-dash memory(operator specific)• combining all CW- sources (PC1, PC2, el. bug, straight key)• well defined PTT- signal (start and stop)

BCC-beverage box

• multiple useage of the same Beverages

• independent remote selection of the wanted direction controlled by multi level DC signals.

• selection principle used since 1989

• CN8WW-Box: two RX outputs per band.

• use of duplexers


page 37

CN8WW-PC-network

• PC-network consisting of 16 stations, Ethernet-hubs, thin-wire back-bone.

• all transmitting trans-ceivers are equipped with remote control interfaces.

• Logging software: CT.927 by K1EA

• Internet-based CLX-system for DX cluster spots.
